Which ADAT ports on my OctoPre MKII Dynamic should I use for 44.1 and 48 kHz sample rates?

This applies to the OctoPre MkII Dynamic

When the OctoPre Mk II Dynamic is set to 44.1 or 48 kHz sample rates, only the right hand optical input (as you face the back of the unit) will function as an input, contrary to the screen printing above the optical inputs. You should connect your optical cable to this optical input.

It will receive 8 channels at this sample rate and feed them to the line outputs provided that the two connected devices are sync'd, working at the same sample rate and the AD DA button on the OctoPre Mk II Dynamic is activated.
